Technologies Used in our Company
IBL develops meteorological systems for professional weather users. Major use case in our
products is visualisation of weather data in form of geospatial maps, graphs or tables with
values or icons. All this content is provided by back-end web services. We intend to build
mobile applications to deliver weather content to general public users as well as professional
meteorologists where much higher level of interactivity is required. We play with the idea of

2. using Xamarin to target all 3 major mobile platforms and reuse code. We use Python to
prototype various functionalities but core of our back-end systems is developed in C++ and
some parts in Java. We usually expose JSON-RPC or RESTful web service interfaces to do
all the clever logic on servers while clients tend to be lightweight, but still non-trivial and
feature reach.
